Weifang Dongyuan Lianhai Environmental Protection Technology Co., Ltd. combines the practical experience of salt chemical companies at home and abroad, and combines various processes such as dehalogenation, evaporation crystallization, vacuum cooling, carnallite controlled decomposition, and other bitter brine recycling. The project has applied a variety of advanced technologies and equipment, such as “halogenation sodium-controlled decomposition crystallization” process, DTB crystallizer technology and other domestic advanced technologies, and built a leading domestic production line. On this basis, our company has independently developed large-particle magnesium chloride technology, which is the first in China. The project came into being under the call of the country to vigorously develop circular economy. The raw materials were taken from a large amount of bitter brine discharged from salt-producing enterprises in the northern coastal areas. After comprehensive treatment and utilization, the zero pollution in the true sense was achieved. The national energy conservation and emission reduction requirements have effectively improved the ecological environment of coastal areas. After inspection and certification by relevant departments, our company has won the title of National Key Encyclopedia of Circular Economy, which is an encouragement to the East China Sea and is also a spur.
